My thanks to Loopt for sponsoring this week’s DF RSS feed. In a nut, Loopt is a location-aware social network that can link to other services like Facebook, Twitter, and Yelp. It lets you do things like find nearby restaurants that are recommended by your own friends. Version 1.1 of their free iPhone app just hit the App Store last night.

Loopt, you may recall, had an on-stage demo during the WWDC keynote this year, which I mocked on Twitter. What was cool is that when they contacted me to inquire about sponsoring the DF feed, they took the jokes in stride, and offered to pay for the ad in polo shirts.
